Application filer. November 19, 1903. Serial No. 181,782. (No model.)

To all whom it may concern.-

Be it known that I, THEODORE OLANS SAMP- son, a citizen of the UnitedStates, residing at Bue, in the county of Nelson and State of NorthDakota, have invented certain new and useful Improvements in Wrenches,of which the following is a specification, such as will enable thoseskilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved wrenchparticularly adapted for use as a pipe-wrench and which is simple inconstruction and operation and comparatively inexpensive; and with thisand other objects in view the invention consists in a wrench constructedas hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in whiel1- Figure 1 is a sectional side view of awrench made according to my invention, and Fig. 2 a plan view thereof.

In the practice of my invention I provide a wrench-handle (4, having aflattened and elongated end member a which in the form of constructionshown is provided with three projecting lugs or ears a I also provide awrench member 7), which is preferably made of steel and which is flat incross-section and the length of which is approximately twice the widththereof, and said wrench member is provided at one end with two lugs orears 6, which fit between the lugs or ears (0 of the handle member a inthe manner of a hinge, and through the lugs or cars a and b are passed ahinge, pin, or bolt 0. The wrench member 6 is also provided at one sidewith a spring-metal plate d, and one end of the hinge, pin, or bolt 0 isprovided with a head 0 and the other is screw-threaded, as shown at c,and the plate (Z is provided with a corresponding hole, through whichthe screw-threaded end of the hinge, pin, or bolt 0 passes, and byturning said hinge, pin, or bolt the plate cl may be caused to operateas a brake, so as to hold the wrench member 7) at any desired angle withreference to the handle a.

The wrench member I) is provided with a V- shaped opening a, formingseparate jaws c and c, and one of these jaws is provided with transverseserrations or teeth a.

The operation is similar to that of other wrenches of this class andwill be readily understood without further description thereof.

One of the chief features of this invention is in the manner of hingingthe wrench member .71 to the handle a, whereby said wrench member may beheld at any desired angle to said handle.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A wrench, comprising a wrench member having jaws the opposite sides ofwhich are parallel, said member being also provided with projecting lugsor ears, and a handle member provided with corresponding lugs or ears,the outer surface of the outer lugs or cars being flush with theparallel sides of said jaws, said wrench and said handle member beingconnected by a bolt passed through the lugs or cars of each, and aspring secured to the outer side of one of said jaws and adapted to bearon the corresponding side of one of the lugs or cars of the handle andthrough which said bolt is also passed, substantially as shown anddescribed.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 14th day ofNovember, 1903.
